To all whomvz't may ,concern v Be it known thatwe, FRANK WoJTKowsiii andDOMINIK RADzIsZEwsKI, subjects of the Czar of Russiapresidin'g atChrome, Ain the county of Middlesex and. State of New Jersey, haveinvented certain newrand useful Improvementsin :Padlocks,of which thefollowing is a specification.

improvements in .padlocks v he ,primary object of this invention is tolprovidea portable lock inthe nature of-a padlock and which requires twokeys for the complete release. of the ylocking lmember or hasp.

A further object is to provide a two key padlock operable` onlyuponmanipulation of each of theeither of theke s. r.

A still further Objectis to provide a padlock having two ymanipulatingkeys, one of the keys being adapted in the unlockingl operation to:retract a boltwhile the other shifts the keeper butin the locking4operation the rst named vbolt engaging` key is solely employed for bothprojecting the bolt and reshifting the'keeper to its locked position.

With these .general objects in view -andothers .that will appear as thenature of the invention is better l understood, the same' consistsin thenovel combination and arrangement of parts hereinafterv fullyldescribed, lillustrated .in the accompanying drawings and pointedoutclaims. f

A partition 39 is provided in the casing at a point between the shelf 26and the bottom wall 40 of the case, the said partition being positionedparallel to both the said shelf and wall and is provided with a centrallongitudinal slot 41 therethrough. A keeper 42 mounted upon an operatingplate 43 is slidably positioned within the casing with the said plate 43slidably mounted in opposite ways 44 carried by the partition 39 andhaving the said keeper 42 extending through the end slot 45 of the.partition 39. T he keeper is provided with a socket perforation 46through its upper portion and the said perforation is at all times inalinementl with the bolt end 33 while a transverse notch 47 of thekeeper is at all .times in alinement with the lower angular end 48 ofthe hasp when the hasp is positioned with its free end within the casingand with its lug 36 engaging the top plate thereof.

Two pins 49 are slidably positioned within yokes 50 carried by thepartition 39 and spanning the slot 41 thereof in such a manner that thesaid pins normallyrest of `their own weight upon the upper surface ofthe keeper operating plate 43 and extending f non as unarmed in. rig. 1.The pme 43 through the said slot while the operating plate is providedwith two spaced transverse perforations 5 1 adapted to receive the saidpins 49 when the keeper is in its locked posiis provided with 'a similarthird perforation 52 farther removed from the keeper 42 than theperforations 51 and the saidperforation 52 is adapted to receive o'ne ofthe pins 49 when the keeper is in its unlocked position and flatlyengaging the inner face of the end wall 53 of the casing as illustratedin Fig.l 2.

When therelements are in their unlocked position as illustrated in Fig.2 and with the hasp inserted within the casing ready to be lockedtherein, the key. 11 may be inserted through the key opening 14 and theward 37 of the key pressed against the pin 49 which Lis within the plateperforations 52 and the y said pin being 'thereby forced out of* thesaid opening, the key 11 may be moved outwardly of the casing anddrawing the operating plate as well as the keeper longitudinally of thecasing and so as to engage the keeper notch 47 with the hasp end 48 inits locked position and at which time the two pins 49 will both dropinto the plate perforations 51 upon removing the said key 11. The key 11will then be inserted through the key-hole opening 13 and upon engagingthe ward 37 with the perforation 38 of the bolt 25, the key may be`pushed inwardly, thus sliding the bolt 45 longitudinally and projectingthe locking end 33 thereof through the hasp perforation 34 and thekeeper socket perforation 46, while upon removing the key 11 the freeend of the spring 284 will drop into the notch 32 of the bolt andprevent a return movement of the bolt moved from the lock. the notches31 and 32 are inclined for affording abutments 54 at their forward endsand sloping rearwardly for allowing the spring 28 to readily ride uponthe bolt during its .projecting movement. l When desired to unlock. theelements, the

. two'keys are employed by inserting the key.

The manner of locking and unlocking the hasp from the casing mechanismhaving been described, it will be understood that the hasp and the chain17 are together employed for encircling the desired elements after the lmanner of the swinging hasp or yoke of the ordinary padlock or -in otherwords, when the hasp is entirely removed fromthe casing, the chain maybe passed around such members as bars or through staples or rings Aandwhen the hasp .is in locked engagement such elements with the casingmechanism, will be firmly secured together.

While the forms vof the invention herein shown and described are whatarebelieved tobe preferable embodiments thereof, itl is nevertheless to beunderstood that minor changes may be made in the form, propori tion anddetails of construction without vde parting from the spirit and scope ofthe invention as set forth in the appended claims.
